Shop GMC K3500 Replacement Exhaust Manifold

The exhaust manifold, otherwise header, is a stainless steel or cast iron component of the GMC K3500 that delivers the engine exhaust from the cylinders to the exhaust pipe. They include a variety of steel tubing which converge into one collector tube. However, there are some variations of exhaust manifolds, and not all include a collector. They can also be coated with ceramic or more heat resistant finishes. The exhaust manifolds are added to reduce flow resistance, and enhance the overall engine efficiency.

The GMC K3500 exhaust headers are direct fit OE replacement ones that have a cast iron construction. They can be added to a variety of GMC K3500 sub model years from 1979 up to 2000. Among the suitable GMC K3500 sub models are: Sierra Grande, Sierra Classic, High Sierra, Base, Sierra SL, Sierra SLE, Sierra SLT and the Sierra SLX with eight cylinder engines.
